At this point, you must awaken three ancients. A Vision of Ysera will appear after each. You must awaken Goldrinn before beginning the Aessina/Tortolla quests but can otherwise work on them in any order.

Be sure to accept the quest right away. I took some time reading it before clicking accept, and the 'Mysterious Winged Spirit' went away. You can't get her to come back either, since you've already used your nectar in the prior quest.

Fortunately I could still get the follow-up quest 'A Wing and a Prayer', so blizzard seems to have allowed for this.

If you abandoned A Plea From Beyond for some reason, or cannot re-obtain it, you can get the quest back by waiting for player to come to the circle to get the quest and ask the player to invite you to a group and share the quest.

Thank you Mesha from Moonglade for helping me re-obtain the quest, Copperleaf.
